 # GitLab CI/CD Examples
 
-Examples are a useful way of understanding how to implement GitLab CI/CD for your specific use case.
+This page contains links to a variety of examples that can help you understand how to
+implement [GitLab CI/CD](../README.md) for your specific use case.
 
 Examples are available in several forms. As a collection of:
 
 - `.gitlab-ci.yml` [template files](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/lib/gitlab/ci/templates) maintained in GitLab. When you create a new file via the UI,
   GitLab will give you the option to choose one of these templates. This will allow you to quickly bootstrap your project for CI/CD.
   If your favorite programming language or framework are missing, we would love your help by sending a merge request with a new `.gitlab-ci.yml` to this project.
-- Repositories with [example projects](https://gitlab.com/gitlab-examples) for various languages. You can fork and adjust them to your own needs.
+- Repositories with [example projects](https://gitlab.com/gitlab-examples) for various languages. You can fork and adjust them to your own needs. Projects include demonstrations of [multi-project pipelines](https://gitlab.com/gitlab-examples/multi-project-pipelines) and using [Review Apps with a static site served by nginx](https://gitlab.com/gitlab-examples/review-apps-nginx/).
